'Open with' File Name.

Hi, I have recently made a backup copy of my QuickBooks Plus Small Business 2008/09 and saved to my ext. hard drive. My Laptop has since had a major upgrade and am trying to restore original files. All was ok but I could not email invoices as previously the case. Print was the only option. I called customer support for advice and was informed I need to delete the Quickbooks programme in its entirety and download another version which I have now completed. I am following the prompts to restore the backup version but am unable to do so as I do not know the file name to open with. Please advise ‘open with’ file name asap so as I can send invoices to clients. Thank you, Regards, Rob Hoffmann Airborn Maintenance (Aust) PTY LTD ABN: 12 127 178 367 MB: 0438441232
